Filter by:The study aim is to compare the pharmacodynamic effects (cardiovascular effects- primary variable: Heart rate over 4 hours post dosing- ) after administration of BDP and formoterol administered as CHF 1535 100/6 NEXThaler DPI or CHF1535 pMDI at two different dose levels.
The main purpose of this study is to determine the feasibility and effects of a 6-month tai chi exercise program as compared to a 6-month group walking program and standard care for patients with COPD that have recently completed a pulmonary rehabilitation program.
Chronic Obstructive Pulmonary disease (COPD) is one of the major clinical entities that causes thousands of deaths every year all over the world and weights a lot on the health care system of every country in terms of direct and indirect costs. The physiopathological modifications that characterise COPD are represented by irreversible (sometimes partially reversible) airflow obstruction, and bronchiolar inflammation. Lungs that develop emphysema lack of elastic recoil and imply increased resistances and airflow obstruction due to loss of lung parenchyma and supporting elastic structures. All these modifications produce air trapping and so lung hyperinflation. The latter is precisely the cause of the symptoms and particularly dyspnoea which is often heavily perceived by COPD patients and that drives to the limitation of daily activities. Lung hyperinflation and the other alterations that occur in COPD imply gas retention and increase in pulmonary vascular resistances. Considering that the rib cage has limited elastic properties, the effects of gas trapping and lung parenchymal damage on mediastinum and particularly on heart mechanics is indisputable. Together with alveolar hypoxia, lung hyperinflation is responsible for the development, as the disease progresses, of the cor pulmonale. Tha latter causes pulmonary hypertension and increased mechanic load during right heart chambers contraction and relaxation. Those alterations may effect left heart chambers too. Airflow obstruction in COPD is usually treated by inhaled bronchodilators and corticosteroids. The main and most used bronchodilators are represented by beta 2 agonists (short, long and ultra-long acting) and anticholinergic inhalatory drugs, which can be also short, long and ultra long acting. Among ultra long acting beta 2 agonists, indacaterol is characterised by quick onset of action (5 minutes), and guarantees an effective bronchodilation duration of 24 hours. It is also known that it has an important effect on reducing lung hyperinflation decreasing residual volume and consequently allowing an increase of inspiratory capacity. The purpose of our study is to evaluate the effects of indacaterol on lung hyperinflation in COPD subjects of any stage and with lung air trapping, and the consequent potential effects on heart performance evaluated by cardiac trans thoracic echo color doppler.
15 COPD patients will be surveyed in this prospective randomized crossover pilot study concerning non invasive ventilation. Patients will be treated over 2 nights in randomized order with Ventimotion2 (Weinmann) with and without Airtrap Control under Polysomnography (PSG) surveillance including transcutaneous pCO2 measurement. The sleep quality is judged by evaluating the PSG and pCO2 values over night. Target parameters are respiratory rate, sleep quality and influence of Airtrap Control on pCO2 values over night.
Home ergometer training combined with online monitoring and regular telephone support could prove to be a cost-effective method to improve physical performance and quality of life in COPD patients. The primary objective of the study is to demonstrate a significantly higher daily workout time in patients that are monitored during home ergometer training with telephone support compared to conventional home ergometer training. Consequently we expect an increased quality of life related to the illness and a decreasing BODE-Index. A post-interventional lower BODE-Index correlates with a reduced risk of hospitalisation and mortality.
Aim of this prospective randomized trial is to compare non invasive ventilation (NIV) with pressure control (BiPAP-ST) to volume assured pressure support (iVAPS) with regards to sleep quality and alveolar ventilation in patients with routine NIV initiation after COPD exacerbation. 20 patients with COPD and chronic hypercapnic respiratory failure will spent two nights on NIV, one with spontaneous timed pressure controlled bilevel ventilation (BiPAP-ST) and one with the advanced mode of intelligent volume assured pressure support (iVAPS). Patients will spend the treatment nights in randomized order under polysomnographic surveillance, including transcutaneous PCO2 measurement. Besides the number of arousals and PCO2 values over night the sleep quality will be judged with regards to especially adjusted respiratory event criteria like unintentional leaks, patient ventilator asynchrony, and decrease of ventilatory drive.
The effectiveness of clinic-based pulmonary rehabilitation in advanced Chronic Obstructive Pulmonary Disease (COPD) is well established, but few data exist for less severe patients treated in alternative settings. The purpose of this study was to investigate whether a novel, community-based exercise program was feasible and effective for patients with moderate COPD.
The main goal of this study is to evaluate the efficacy and safety of glycopyrronium bromide and indacaterol maleate and glycopyrronium bromide fixed dose combination (FDC) in patients with moderate COPD who switch from their current COPD therapy. This study aims to provide data on how non-exacerbating, but still symptomatic patients with moderate COPD switching from their current COPD treatment to glycopyrronium bromide or indacaterol maleate and glycopyrronium bromide FDC maintain or improve their symptoms. Another purpose of this study is to increase awareness and usage of validated COPD symptoms tools and dyspnea questionnaires in order to facilitate clinical assessment and improve early diagnosis of symptomatic patients.

The Physical Functioning Inventory (PFI) is a standardized patient reported outcome measure that assesses preclinical disability. Preclinical disability is a functional state in which people are still able to complete daily living tasks (e.g., walking, bathing) but are changing the frequency or modifying the way that they complete the tasks. The investigators have done some preliminary research using the PFI as an online monitoring tool (Richardson 2012), but further study is required to examine its psychometric properties and its suitability for use as a primary outcome measure. This measurement study has been designed to identify the optimal number of items on the PFI and to determine the reliability, validity, and responsiveness of the PFI when administered to a sample of adults and older adults both with and without chronic conditions. This project will also allow us to evaluate the use of self-monitoring of physical function and the added value of rehabilitation professionals to support self-monitoring. Using the results of the PFI, the investigators aim to develop a "tailored" population-based rehabilitation self-management intervention delivered through a secure messaging system in the patient's electronic personal health record (myOSCAR) that focuses on the early detection and prevention of preclinical disability.
